Spatial integration at multiple scales: rice markets in Madagascar

The dramatic increase in the price of rice and other commodities over the past year has generated new interest in how these markets work and how they can be improved. This article uses an exceptionally rich data set to test the extent to which markets in Madagascar are integrated across space at different scales of analysis and to explain some of the factors that limit spatial arbitrage and price equalization within a single country. We use rice price data across four quarters of 2000–2001 along with data on transportation costs and infrastructure availability for nearly 1,400 communes in Madagascar to examine the extent of market integration at three different spatial scales—subregional, regional, and national—and to determine whether non-integration is due to high transfer costs or lack of competition. The results indicate that markets are fairly well integrated at the subregional level and that factors such as high crime rates, remoteness, and lack of information are among the factors limiting competition.     

Value-based partnering in health care

Many companies are beginning to focus on value in their health care purchasing decisions, and some are going beyond value-based purchasing to value-based partnering. Value-based partnering recognizes the interdependencies among stakeholder groups in the health care system and creates a strategic reason for them to exchange information and create long-term strategic alliances. This article discusses the principles of value-based partnering, impediments to practicing it and its future role in the health care system.     

Linking Website Interactivity to Consumer Behavioral Intention in an Online Travel Community: The Mediating Role of Utilitarian Value and Online Trust

Although prior studies have shown that perceived website interactivity plays an important role in positive behavioral intentions of online customers, the underlying psychological mechanisms remain unclear. Therefore, the purpose of this study was to examine the mediating role of utilitarian value and online trust in relationship between perceived website interactivity and repurchase intention in an online travel community. Data were collected from 227 customers who had purchased travel-related products on any online travel website within the past 12 months. The empirical results supported all study hypotheses. As predicted, utilitarian value and online trust fully mediate the relationship between perceived website interactivity and repurchase intention. Theoretical and practical implications are discussed.     

Persistent poverty and informal credit

This paper explores the consequences of nonlinear wealth dynamics for the formation of bilateral credit arrangements to help manage idiosyncratic risk. Using original data on expected wealth dynamics, social networks and informal loans among southern Ethiopian pastoralist households, we find that the threshold at which expected wealth dynamics bifurcate serves as a focal point at which lending is concentrated. Informal lending responds to recipients' losses but only so long as the recipients are not “too poor”. Our results suggest that when shocks can have long term effects, loans are best understood as providing a safety net rather than a scale-neutral insurance mechanism. Furthermore, the persistently poor are excluded from social networks that are necessary to obtain loans given in response to shocks.     

Changes in subjective well-being with retirement: assessing savings adequacy

Does retirement represent a state of relative prosperity or unanticipated hardship? To assess whether individuals are successful in smoothing their well-being across the transition to retirement we analyse measures of subjective well-being (SWB) in the Household, Income and Labour Dynamics in Australia (HILDA) Survey. Specifically, this research examines retirees’ current standard of living, financial security and overall happiness relative to their pre-retirement levels. It is found SWB either improves or remains constant for the large majority of individuals as they retire from the labour force. However, there are significant disparities in changes in well-being with retirement among the group of retirees. In particular, the subset of individuals who are forced to retire early due to job loss or their own health, and who find their income in retirement to be much less than expected, report marked declines in their SWB with retirement.     

Environmental Regulation For Competitive Advantage

The public's increasing demand for environmental protection will inevitably increase the demands for environmental regulation. But this need not be bad news for industry. Companies will often find that their interests coincide with those of the regulators, and astute players will try to shape the regulation accordingly.     

Taxi Sharing: Belfast leads London

Nicholas Ridley, Secretary of State for Transport, is loosening the market by deregulating road transport. He could intensify competition to 'public' bus services by relaxing the regulation of taxis, as two Irish economists demonstrate from the example of Northern Ireland.     

Some Loans Are More Equal than Others: Third–Party Originations and Defaults in the Subprime Mortgage Industry

We show how agency problems between lenders (principals) and third–party originators (TPO; agents) imply that TPO–originated loans are more likely to default than similar retail–originated loans. The nature of the agency problem is that TPOs are compensated for writing loans, but are not completely held accountable for the subsequent performance of those loans. Using a hazard model with jointly estimated competing risks and unobserved heterogeneity, we find empirical support for the TPO/default prediction using individual fixed–rate subprime loans with first liens secured by residential real estate originated between January 1, 1996, and December 31, 1998. We find that apparently equal loans (similar ability to pay, option incentives and term) can have unequal default probabilities. We also find that, initially, the agency–cost risk was not priced. At first, the market did not recognize the higher channel risk, since TPO and retail loans received similar interest rates even though the TPO loans were more likely to default. We also show that this inefficiency was short–lived. As the difference in default rates became apparent, interest rates on TPO loans rose about 50 basis points above otherwise similar retail loans.
